Sandvik discusses turbochargers

Published by , Assistant Editor

Sandvik’s face milling cutter has been exclusively developed for machining of turbo exhaust housings in turbochargers. The turbocharger is essentially a gas-driven turbine that rotates at over 300 000 rpm. By compressing a large volume of ambient air for combustion, it makes a vehicle’s engine run cleaner and more efficiently.

The exhaust side housing in a turbocharger must be able to operate in temperatures ranging from 850 to more than 1300°C. The heat-resistant materials and other technologies, such as aerodynamics, rotor dynamics and testing procedures, are not unlike those used in the aerospace industry.

Turbocharging is key for enabling increased vehicle power density – getting more output from smaller engines. With demand for smaller engines increasing, some 85% of all new light vehicles in Europe are likely to be turbocharged by 2020.
